FASTENER FOR VENTILATORS.

Application filed May as, 1924. Serial No. 716,040.

The invention relates to fasteners for ventilators and for one of its objects the provision of an improved fastener in which the handle is frictionally held in its various positions of adjustinent;v Another object is to provide a fastener'in which a common means frictionally engage the handle and forms a nut for thebolt upon which the handle is journaled. Further objects of the invention reside in the novel features of conshaped cross-section, each rail having an inner flange 2 forming a seatfor the glass 3. 4 is the frame having the opening in which the ventilator is engageable for closing the same. The bars forming this frame are also preferably of substantially Z-shaped crosssection and arranged so that their flanges are engaged by the flanges of the sash-rails when the ventilator is in closed position.

To secure the ventilator in closed position or a slightly open position, I have provided a fastener secured to the side rail of the sash at its swinging edge and engageable with the adjacent side bar of the frame. This fastener is so assembled that the support for the handle may lie in close PTOX? imity to the glass and the handle may be readily removed or applied without extra tools or danger of breaking the glass.

In detail, 5 is a bracket having the body 6 in the plane of and occupying an opening in the flange 2 of the side rail of the sash, the transverse flange 7 riveted to the web 8 of the side rail and the off-set flange 9 extending parallel to the body but laterally off-set inwardly therefrom. 10 is a handle having the boss 11 the inner side of which engages the off-set flange 9. 12 is a bolt extending through the boss 11 and the off-set flange 9 and upon which the handle is journaled. 13 is a laterally extending lug upon the handle near its journal and having an end cam surface 14 movable over the side bar of the frame 4;. 15 .isa resilient yoke having one arm 16 enlarged at its end and located between the bolt head and the handle hub. and the other arm 1'? enlarged at its end and threadedlj engaging the inner end of'the bolt. This latter arm is located between the offset flange 9 of the-bracket and the glass 3; To retain the yoke from rotation relative to the brac ret, thev off-set flange 9 is cut away at 18 to be engagedfin by the base or intermediate portion 19 of the yoke. r

WVhen the parts are assemblechthe arms of the'yoke are adjusted toward each other to place the yoke under compression, as a result the arm 16 as well as theotf-set flange 9 frictionally engagetheboss 11 of the handle to retain the latter in its various positions of rotative adjustment .Also this friction opposed to the rotation of the handle is constant, with the exception of decrease owing to wear, since the yoke is held from rotation.- Another favorable result of this assembly is that the arm 17-of the yoke functions asacombined nut and lock washer owing to the, fact that this arm threadedly engages the bolt 12 andhas' a tendency to spread. away from the, otherarm, thereby placing an extra stress upon thc inner sides of the bolt threads. 9

The laterally extending lug 13 is provided in its edge with the notch 20 for engagement in by the edge of inner flange of the frame side bar whereby the ventilator may be held in slightly open position.

For, the purpose of providing an improved bearing surface for engagement with the cam surface 14 of the laterally extending handle lug there is the rivet 21 upon the frame side bar. This rivet has the flattened head 22 located to be engageable by the cam surface.

To limit the rotation of the handle into fastening position I have provided the transverse pin 23 near the journal of the handle and engageable with the cut-away edge of the off-set flange 9 of the bracket.

From the above description it will be readily seen that I have provided an improved fastener which comprises but few parts andwhich is so formed that it may project but the minimum distance from the glass of the ventilator. Also the assembly of the fastener permits ready attachment or removal of the handle to or from its sup port without special tools and without danger of breaking the glass. Furthermore the construction opposes a constant frictional resistance to rotation of the handle and the bolt upon which the handle is journaled or pivot for the handle is secured in place by a member which functions as acombined nut and lock washer.

What I claim as my invention is:

1. The combination of a support, a handie at one side of said support, a pivot for said handle extending through said handle and support and provided with a head at one end and a threaded portion at the other end, and a resilient yoke embracing said handle and support and having a portion threadedly engaging said pivot threaded portion and another portion abutting said pivot head.

2. The combination of support, a handle at one side of and engaging said support, a bolt extending through said handle and support, and a resilient yoke having a por tion engaging the head of said bolt and said handle and another portion threadedly engaging said bolt at the opposite side of said support.

3. The combinationof a support, a handle'at one side of and engaging said support, a bolt extending through said handle and support, and a resilient yoke having one arm located between said handle and the head of said bolt and another arm threadedly engaging said bolt at the opposite side of said support, and means for holding said yoke and support from relative rotation.

4:. In a ventilator the combination with a sash having a side rail providing a seat for a glass, of a support upon said side rail having a portion off-set laterally fromthe glass, a handle at the opposite side of and engaging said oil-set portion of the support, a bolt extending through said handle and olf-set portion, and a resilient yoke embracing said off-set portion and handle and having an arm located between the head of said bolt and said handle and another arm threadingly engagin said bolt between V o off-set portion and the glass.

5. The combination of a support, a handle,

said a a bolt extending through said support and handle.

6. The combination of a support, a handle,

a bolt extending through said support and handle and a member held from rotation by said support and engaging said handle to offer frictional resistance to rotation of the latter, said member also engaging said bolt and offering frictional resistance to rotation of the same. i

7. The combination of a support, a handle, a pivot upon said support for said handle, and a member having portions at opposite sides of said support and offering frictional resistance to rotation of said handle relative to said support.

8, The combination of a support, a handle,

a pivot upon said support for said handle w and provided with a head, and a member having a portion engaging said support and another portion between said head and hanc le.

9. The combination of a support, a handle, a pivot upon said support for said handle, and adjustable means embracing said support and handle and fixed against rotation with respect to said support for offering frictional resistance to rotation of said handle. v

10. The combination of asupport, a handle at one side of said support, a bolt extending through said support and handle, and a member secured to said bolt on the side of said support opposite said handle, said' memberlextending around said support and handle for frictionally resisting rotation of said handle.

In testimony whereof I a'fiix my signature.
